RoCE at a Crossroads (2013)
iWARP is the no-risk high performance solution for 40Gb Ethernet clustering, leveraging TCP/IP’s mature and proven design, with the required congestion control, scalability and routability, preserving existing hardware and requiring no new protocols, interoperability, or long maturity period. RoCE in contrast is an expensive journey of experimentation, rediscovery and frustration that would take years to complete, if it ever does.
